The current state-of-the-art in silicon nanophotonic ring resonators is reviewed. The basic theory of ring resonators is discussed, and applied to the peculiarities of submicron silicon photonic wire waveguides: the small dimensions and tight bend radii, sensitivity to perturbations and the boundary conditions of the fabrication processes. Theory is compared to quantitative measurements. Finally, several promising applications of silicon ring resonators are discussed.
